Re: [dns-operations] Current thinking on internal corporate/campus domain names

2014-06-24 Thread Kelly Setzer
Summary:

Thank you all very much.  There were seven respondents.  Here are the key
points.

* There is a fourth option for internal DNS, that being use of a subdomain
of the corporate domain, e.g., int.mycorp.com.

* Several reiterated that use of a fantasy TLD could collide with current
or future TLDs.

* One respondent made several great points that I would summarize as,
³Plan ahead.  Factor Internet connectivity into the plan.²

* .local is no longer viable, Microsoft no longer recommends it.

* I received this specific, interesting suggestion: Register a domain,
but delegate it to DNS servers that are not in your network and always
contains a null-zone.

* It is not possible to obtain SSL certs (from commercial CAs) unless the
internal domain is registered.  This makes .corp potentially unusable.


* Most respondents agreed that a registered domain for internal DNS was
the way to go.


As a result of your input and related research, I¹ll be recommending the
use of a registered domain for internal DNS for the project I¹m working on.

Cheers,
Kelly

[dns-operations] Current thinking on internal corporate/campus domain names

2014-06-23 Thread Kelly Setzer
What is current thinking/accepted practice for internal domain names?

* Registered domain name (e.g., somecompany.com)
* Fantasy tld (e.g., .mycorp)
* .local (collides zeroconf/mDNS)

This is for use within a corporate/campus setting.  In times past, I have
taken the fantasy approach.  However, colleagues have pointed out that the
growing list of new gTLDs and branded TLDs could collide with a fantasy
TLD.

RFC 2606 seems to suggest using a registered domain.  That¹s great except
that split-brain inevitably creeps into the equation.  Is this a case of
choosing the ³least worst² option?

Thanks,
Kelly

[dns-operations] Sprint DNS contact

2012-09-26 Thread Kelly Setzer
I am a Sprint customer but I am having problems finding someone at Sprint who 
speaks DNS.  Sprint has an SOA record in place for one of my domains that was 
moved to other NS long ago.

If someone has a contact or if Sprint monitors this list, please get in touch.

thanks,
Kelly
